Abstract

A device for wireless, non-line-of-sight delivery of a signal from a coaxial cable to a transceiver at an end user device comprises a signal enhancement and prioritizing module which converts the signal into a wireless signal which comprises less data than the signal, and an antenna which broadcasts the wireless signal to at least one end user device transceiver, wherein the wireless signal has the capability to transfer data to the at least one end user transceiver at a rate of greater than 40 Mbit per second. In accordance with another aspect the signal enhancement and prioritizing module comprises an admission control unit module which processes variable bit rate information to determine whether a wireless signal may be transmitted to a particular client end user device, a dynamic scheduler module which processes variable bit rate information to determine when the wireless signal may be transmitted to a particular client user device, and a packet scheduling and retransmission module having forward error correction which is variable depending upon a condition of the wireless signal.

Claims

1. A device for wireless, non-line-of-sight delivery of a signal from a coaxial cable to a transceiver at an end user device comprising, in combination:

a signal enhancement and prioritizing module which converts the signal into a wireless signal which comprises less data than the signal, and

an antenna which broadcasts the wireless signal to at least one end user device transceiver, wherein the wireless signal has the capability to transfer data to the at least one end user transceiver at a rate of greater than 40 Mbit per second.

2. The device of claim 1 wherein the wireless signal has the capability to transfer data to multiple end user transceivers at a rate of greater than 150 Mbit per second.

3. The device of claim 1 wherein the end user device comprises one of a personal computer, a laptop and a television.

4. The device of claim 1 wherein the wireless signal is broadcast on an unlicensed frequency.

5. The device of claim 1 wherein the signal is not broadcast to at least one end user device transceiver.

6. The device of claim 1 wherein the signal enhancement and prioritizing module comprises an encoder which splits the signal into a base stream and at least one enhancement stream.

7. The device of claim 1 wherein the signal is reduced to the wireless signal based on a demand from the end user device.

8. The device of claim 1 wherein the signal is reduced to the wireless signal based on a limiting instruction from the signal enhancement and prioritizing module.

9. The device of claim 1 further comprising a tuning module comprising a video tuning module for tuning video data of the signal and a Docsis cable modem for internet access data.

10. The device of claim 1 further comprising an analog to digital converter which converts an analog portion of the signal to a digital signal.

11. The device of claim 1 wherein the signal comprises video data, internet access data and voice data.

12. The device of claim 1 further comprising a point of deployment module which decrypts encrypted portions of the signal.

13. A device for wireless, non-line-of-sight delivery of a signal from a coaxial cable to a transceiver at an end user device comprising, in combination:

a signal enhancement and prioritizing module which converts the signal into a wireless signal which comprises less data than the signal, wherein the signal enhancement and prioritizing module comprises an admission control unit module which processes variable bit rate information to determine whether the wireless signal may be transmitted to a particular client user device; and

an antenna which broadcasts the wireless signal to at least one end user device transceiver.

14. A device for wireless, non-line-of-sight delivery of a signal from a coaxial cable to a transceiver at an end user device comprising, in combination:

a signal enhancement and prioritizing module which converts the signal into a wireless signal which comprises less data than the signal, comprising a dynamic scheduler which processes variable bit rate information determines when the wireless signal may be transmitted to a particular client user device; and

an antenna which broadcasts the wireless signal to at least one end user device transceiver.

15. A device for wireless, non-line-of-sight delivery of a signal from a coaxial cable to a transceiver at an end user device comprising, in combination:

a signal enhancement and prioritizing module which converts the signal into a wireless signal which comprises less data than the signal, wherein the signal enhancement and prioritizing module comprises forward error correction which is variable depending upon a condition of the wireless signal; and

an antenna which broadcasts the wireless signal to at least one end user device transceiver.

16. The device of claim 15 wherein the end user device monitors the wireless signal strength at periodic time intervals and selects one of several possible FEC rates.
